Dev Build 2112 is available now. It's mostly a miscellaneous collection of fixes and tweaks, but a couple of things are worth pointing out:

When undoing typing, no more than a word will be undone at once. This should make guessing what undo will do more predictable.

There have been some non-trivial changes to some of the core text buffer related code, mostly in preparation for an upcoming feature. There's a larger than normal chance that new regressions have been introduced this build: lookout especially for any text layout related regressions.

I think I still have the issue of "solid indent guides not rendering crisply with sub-pixel glyph positioning", at indentation levels 3 and above. I discovered "font_options": "subpixel_antialias"] and added it to my file settings and restarted but it still persists (see screenshot).
